=0A<= div>A couple of years ago, I made a = =0Apost identifying a superior -and much lower cost- Measurement = =0ASpecialties Products (MSP) transducer as a replacement for the Hone= ywell =0AMediMate transducer that the VMS 1000 employs for fuel pressure in= dication. Some =0Atried to use that same transducer for oil = pressure and reported =0Athat it didn't work, yielding a value twice the ac= tual oil pressure. =0AHere's why:
=0A
The 50 psi Honeywell= unit that VMS =0Aemployed for fuel pressure has a 50mV full outp= ut, which equates to =0A1mV/psi. The= 100 psi MSP unit that I recommended =0Ahas a 100mV full output, which also= equates to 1mV/psi; so it functions =0Aperfectly as a replacement for *fue= l pressure*.
=0A
The 100 ps= i Honeywell unit that VMS employs for oil =0Apressure also has a 50mV full = output but, in this case, that equates to =0A.5mV/psi. With it's<= /font> 1mV/psi output, the =0Asame MSP= unit will not function for oil pressure; it causes an =0Aindication d= ouble the actual oil pressure. =
As stated in my post a couple of years ago, the Honeywell =0AMediaMate = is older and inferior technology, prone to failure, and -at over $400- =0Ai= s outrageously priced. In contrast, the MSP unit is compact, superior and = =0Amodern technology at only $120.
=0A
There's another, almost identical MSP unit that has = =0Aa 50mV full output and, consequently, will function perfectly for f= uel and =0Aoil pressure in it's 50 and 100 psi versions. Here's the spec sh= eet: http://www.meas-spec.com/downloads/US300.pdf
=0A
Problem is that the combina= tion of it's 5VDC =0Asupply voltage and 50 mV output is rare= ly utilized in =0Aindustry, so there aren't now any available. Ho= wever, I contacted one =0Aof MSP's distributors and they appear willin= g to place an =0Aorder for the 10 unit minimum, provided that the= re's interest.
=0A
Let me k= now if you're interested, even to purchase =0Aone now for future use if you= r current transducer should fail.
